To investigate the applicability of hot water extract from Codonoposis lanceolata (CL) and fermented Codonoposis lanceolata (FCL) as functional food and cosmeceutical material, its total phenolic contents, total flavonoids, electron donating ability (EDA), SOD-like activity, nitrate-scavenging ability (NSA), reducing power were examined. Total phenolic contents of CL and FCL were 0.54 mg/100 g and 2.79 mg/100 g, respectively, and total flavonoids contents were estimated as 2.26 mg/100 g for CL and 6.16 mg/100 g FCL. The EDA of CL and FCL were 8.0~17.9% and 32.9~74.9%. The SOD-like activities of CL and FCL were 0.6~16.5% and 3.5~21.6%, respectively, and the activity was dependent on the sample concentration. The NSA was pH dependent, and was the highest at pH 1.2 and the lowest at pH 6.0. The NSA of FCL was higher than that of CL. The FCL extract showed the highest reducing power (0.65) at the concentration of 1,000 μg/mL. Based on the above results, we deemed that the FCL might have potential antioxdant activities.

In this study, Life Cycle Assessment(LCA) has been carried out to evaluate the environmental impacts of a metallic can. A 360 mL volume of an aluminum can bottle was used as the functional unit. The results of Life Cycle Inventory(LCI) showed that iron ore and coal were the major parts of the input materials, whereas aluminum can products, carbon dioxide, wastewater, and hazardous wastes were those of the output ones. According to LCA weighting, it was observed that the most significant impact potential was found to be global warming(49.11%) followed by abiotic resource depletion(47.72%). In the whole system, cold rolled steel coil showed the largest environmental impact potential(86%), followed by electricity(14%). Meanwhile, lubricating oil and industrial water had the minor portion of the total environmental impact potentials. It was suggested that the use of cold rolled steel and electricity should be the main source for CO2, resulting in the big impact on global warming.
